I am currently working as a research associate at the Institute for Mathematical Sciences of Imperial College London, with joint positions in the departments of Mathematics, Physics, Neuroscience and Bioengineering. My research project has a broad focus and deals with the relation between dynamics and structure in complex networks, with potential applications in the analysis and modelling of neuronal and social systems.
